Jurassic Park is a satirical comedy about capitalism. Hammond spares every expense. The first scene is a man being killed on the job. He built the park in a country with cheap labour and low safety standards. He essentially had 3 people running the park. They bred raptors just because they could and he put his own grandkids (a metaphor for the future) in danger due to his own hubris and ego. They are literally man made monsters in an amusement park created by exploiting nature using untested technology. The metaphor for the dangers of greed could not be more on the nose, and I'm baffled it isn't more commonly understood.
